Question

Simplify: 2{10-5+x[1+3(6-2)]}

Answer 1

10+26x

Explanation:

To solve this, work your way from the inner most parentheses to the outer most:

1. The inner most parentheses is around 6-2, meaning you solve this first. When you solve this, you get 4.
2. The second most inner parentheses is around (1+3 times 4) using PEMDAS, you first solve the multiplication, and then add. Once you solve this, you get 13.
3. Next, the outer most parentheses is around (10-5+13x). When you simplify this, you get 5+13x
4. Finally, you multiply 2(5+13x). Using distributive property, you get 10+26x as your final simplified answer.
